Postcard Promotions

I'm still in the middle of promoting my Kickstarter campaign to fund my puppet movie and have a lot of postcards left over to help spread the word. Does anyone have any experience with getting these types of things into record stores/coffee shops/comic stores? I know that a lot of places have areas at the front of the store for this sort of thing for bands and festivals, etc. but I'm not sure what puppet-related places might be available. Any ideas?

I'm in the Los Angeles area, but if you have a venue you think you might be able to get some into, O can mail 25 or so out if you don't helping to spread the word! It's a kid-friendly feature-length puppet film. More info can be found here:
